Trust in Allah After Taking the Decision

Being a Muslim we should rely all our trust in Allah (Azawajal) not something else

Allah's statement,

فَإِذَا عَزَمْتَ فَتَوَكَّلْ عَلَى اللّهِ

Then when you have taken a decision, put your trust in Allah,

means, if you conduct the required consultation and you then make a decision, trust in Allah over your decision.

إِنَّ اللّهَ يُحِبُّ الْمُتَوَكِّلِينَ

certainly, Allah loves those who put their trust (in Him).

إِن يَنصُرْكُمُ ٱللَّهُ فَلَا غَالِبَ لَكُمْۖ وَإِن يَخْذُلْكُمْ فَمَن ذَا ٱلَّذِى يَنصُرُكُم مِّنۢ بَعْدِهِۦۗ وَعَلَى ٱللَّهِ فَلْيَتَوَكَّلِ ٱلْمُؤْمِنُونَ 

If Allah should aid you, no one can overcome you; but if He should forsake you, who is there that can aid you after Him? And upon Allah let the believers rely.
